Heterodimers of Nanoparticles:  Formation at a Liquid−Liquid Interface and Particle-Specific Surface Modification by Functional Molecules

On the basis of a fundamental property of nanoparticles, the self-assembling at a liquid-liquid interface to form "colloidosomes", a heterogeneous reaction takes place on the exposed surface of the nanoparticles to produce the heterodimers of two distinct nanospheres, which can be modified by two different functional molecules in a particle-specific manner.
